I created the GPO, applied it to an OU but a couple of things are not working. On my pc, the screensaver timeout is not working. in the GPO I have it set for 10 minutes but it is not overriding my local machine screensaver timeout? It does apply the correct SCR for me, which leads me to the other issue, for me it works but for others in the group it looks like it is pulling from their pictures folder. the syntax I am using for that is: \\servername\share\share\screensaver.scr
If it is a user GPO, all users must be under the corresponding OU.
The GPO must be readable by the corresponding users (if you set a group filtering), but also also by All computers.
Of the file and the share must set with permissions for Users (and computers).
